Home Network
Cloudflare for Families (1.1.1.3)
Set two DNS addresses on your router to filter adult sites and malware for connected devices. The service is free; allow about 5 minutes for setup.
About home network controls
Router and DNS controls apply to every device on your home network simultaneously, including phones, tablets, laptops, smart TVs and gaming consoles, without installing anything on each device. Set them alongside the controls on each device.
What network controls cannot do: They do not work when children switch to mobile data (4G/5G) instead of home WiFi. A VPN app on a child's phone bypasses DNS filtering. HTTPS prevents routers from reading page content: they can only block or allow entire domains, not individual pieces of content within a site.

Complete setup guide
- 1
Log into your router admin panel
Open a browser and go to 192.168.1.1 or 192.168.0.1. The username and password are printed on the label attached to your router. Look for a sticker on the back or bottom.
- 2
Find the DNS settings
Look for a menu item called Internet, WAN, Advanced, Network, or DNS. The exact location varies by router brand. Find the fields labelled Primary DNS and Secondary DNS.
- 3
Enter the Cloudflare for Families addresses
Set Primary DNS to 1.1.1.3 and Secondary DNS to 1.0.0.3. These are different from standard Cloudflare DNS. The .3 addresses specifically include family filtering.
- 4
Save settings and restart the router
Click Save or Apply, then restart the router by unplugging it for 10 seconds. The change applies to every device on your WiFi automatically.
- 5
Test that it is working
On any device connected to your WiFi, try to visit a known adult site. It should be blocked with a Cloudflare block page. That confirms the filter is active.

Note the limitation for conversations
Tell your child that the home WiFi now filters adult content. Frame it as a household standard, not a punishment. They will likely discover it on their own, so it is better that they hear it from you first.
Tip
This is the highest-impact action on the page relative to the effort required. Five minutes, free, and it protects every device simultaneously, including the PlayStation and smart TV that no app-based control reaches.
Warning
Cloudflare for Families does not work when your child switches to mobile data. It also cannot inspect content inside a site: it blocks or allows entire domains. A child on filtered WiFi can still access inappropriate YouTube videos because YouTube itself is an allowed domain.
